An ink-jet recording apparatus which includes a recording medium for carrying an electrostatic image, an ink-ejecting section opposing the recording medium and located in non-contact state with respect to the recording medium medium, and having an ink holding section for holding ink and an opening section for ejecting ink, at least one counter electrode located in the ink-ejecting section to be immersed in ink. The ink is ejected by virtue of an electric field between the electrostatic image formed on the recording medium and the counter electrode.

Ink-jet recording apparatus which allows shifting or changing of ink

In an ink jet system, first and second main electrodes are arranged on an insulating substrate board so as to be extended to one side of the board and connected to first and second auxiliary electrodes through photoconductive sections, respectively. An ink reservoir is formed on the board and an optical system is located above the photoconductive sections. First and second control electrodes are arranged along the one side of the board in an ink jet port of the reservoir so as to face the main electrodes. A back electrode is arranged as to face the ink jet port. First and second control pulse signals synchronized with each other and having pulse and negative polarities are supplied to the first and second control electrodes, first and second high voltage pulse signals synchronized with each other and having pulse and negative polarities are also supplied to the first and second auxiliary electrodes and another high voltage signal having a twice cycle period as that of the control pulse signal is supplied to the back electrode. The potentials on the main electrodes are varied according to the resistance of the photoconductive sections and an ink is jetted from the port to the back electrode when a predetermined potential difference between the main electrode and the back electrode is produced.

An ion flow modulator with high reliability used in a photocopying machine to obtain a high quality image. The ion flow modulator includes an insulating substrate, a common electrode formed on one major surface of the insulating substrate, a plurality of ion flow control electrodes formed on the other major surface of the insulating substrate, a photoconductive layer formed on the insulating substrate and connected to one end of each of the ion flow control electrodes, a first voltage application electrode formed on the insulating substrate and connected to the photoconductive layer, a resistance layer formed on the insulating substrate and connected to the other end of each of the ion flow control electrodes so as to interpose the ion flow control electrodes between the photoconductive layer and the resistance layer, a second voltage application electrode formed on the insulating substrate and connected to the resistance layer, and a DC power source for applying voltages having opposing polarities to the first and second voltage application electrodes. The ion flow passage holes are formed through the insulating substrate and the common electrode. A means is provided for generating ions to pass through the ion flow passage holes.
